| LI.FI builds a DeFi middleware for the application layer. A bridge & DEX aggregation protocol abstracts away the most crucial financial infrastructure to move in and out of any position on any chain — the one gateway to access all DeFi. Whoever (e.g. TradFi) wants to deal with crypto today is forced to deal with a multi-chain environment. Even the most basic liquidity flow requires connecting RPCs, cross-chain bridges, DEXs and DEX aggregators, token lists, gas estimation APIs, and relayer networks. This already complex solution bears the additional need for monitoring, analytics, and fail-safety. | $5.5M / Jul 11, 2022 | ||
